... and then write a custom conditional formatting rule and make your evaluation...

Is there an example for this?  

Hi, i craeted custom rule where i am passing my styles which are created dynamically depeding upon user setting of color for background and foreground. however even after setting the rule property

MyRule.ShouldRefreshOnDataChange = true;

the rule is applied only at first time while loading grid with data. when i start realtime update it does not change depending on rule.

can you tell me where i am going wrong.

my code is something like this

ConditionalFormattingRuleBase

; }

; }

; }

obj)

{

.StyleUp = Styleup;

.StyleDown = Styledown;

objUpDownColourRuleConfig = obj;

}

CreateProxy()

{

(StyleUp, StyleDown, objUpDownColourRuleConfig);

}

}

ConditionalFormattingRuleBaseProxy

; }

; }

; }

obj)

{

.StyleUp = Styleup;

.StyleDown = Styledown;

objUpDownColourRuleConfig = obj;

}

NewDataObject)

{

)

{

;

)OrigDataObject;

));

));

(iNewVal > iOrigVal)

{

.StyleUp;

}

(iNewVal < iOrigVal)

{

.StyleDown;

And i am dynamically adding the rule from code behind lke this

#region

Up/Down Colour Rule

Dictionary<string, UpDownColourRuleConfig> dictUpDownColorRuleConfig = viewmodelobj.dictUpDownColourRuleConfig;

if (dictUpDownColorRuleConfig != null && dictUpDownColorRuleConfig.Count > 0)

{

this.dataGrid.ConditionalFormattingSettings.AllowConditionalFormatting = true;

foreach (var item in dictUpDownColorRuleConfig)

{

Color forecolorUp = new Color();

forecolorUp.A = 255;

byte.Parse(item.Value.RuleUpForeColor.Substring(0, 2), NumberStyles.HexNumber);

forecolorUp.G =

UpDownConditionalFormatRule MyRule = new UpDownConditionalFormatRule(styleUp, styleDown, item.Value);

Does your data object implement INotifyPropertyChanged? 

There is no reply to my query yet.

This is a very basic requirement for any trading application.Even after creating the custom rule it does not get appied to real time data change...even after setting the

MyRule.ShouldRefreshOnDataChange =

true;

i am waiting for your reply since past four days.

i am unable to find the following dlls so unable to run your test project.i am using Vesion 10.3.

Infragistics.Silverlight.dll

Infragistics.Silverlight.XamWebGrid.dll

Those are the two dlls for the XamGrid.  You would need to add those references.
